Wind Generation

MidAmerican Energy will add up to 1,050 MW of wind generation, consisting of up to 656 new wind turbines, in Iowa by year-end 2015. If the expansion is approved by the Iowa Utilities Board, MidAmerican Energy will own and operate approximately 3,335 MW of wind generation capacity in Iowa by year-end 2015.

New technologies—and new expectations—require taking a fresh look at the institutions and practices that have provided reliable electricity for the past century. Collective action is needed to define the key attributes of a future grid and then to take the more difficult next step—adapting our processes and institutions to align with that future vision. A thoughtful approach will allow America to capture the potential value that’s offered by sweeping changes in technologies and policies.

New York has developed new market mechanisms intended to effectively incorporate large amounts of renewable energy in the future — up to six times the current levels of intermittent energy without impacting system reliability. New York ISO executive Rana Mukerji explains how the market will drive new investment in renewable energy in the state.

Market rules could evolve to compensate gas suppliers for pressurizing pipelines when needed on short notice. Enhanced ancillary services will require innovative strategies using line pack in interstate pipelines and stepped up communication among gas and electric market participants to preserve reliability objectives in gas and electric markets.

Photovoltaic technologies are beginning to appear more attractive than concentrated solar thermal plants. PV’s competitiveness is improving from technical and operational advancements, as well as significant commitments made by such utilities as Southern California Edison. In the long run, distributed central PV plants likely will gain a strong market position.

The federal government and several state governments are considering programs to increase the share of electricity produced by renewable generation resources to 20 percent or more. If these programs are implemented and pursued successfully, they will trigger a dramatic change in the role of renewable generation and the requirements placed upon it by the market.
